Abstract The Major histocompatibility complex (MHC) plays a central role in the vertebrate immune system. The protein products of MHC genes present foreign peptides to T-cells, which then initiates the appropriate immune responses. MHC genes show extreme level of polymorphism and this was suggested to be maintained by selective pressures exerted by various parasites. Although associations between

While more and more businesses incorporate sustainability in their core business strategy, there has recently been a shift from corporate social responsibility (CSR) to the notion of creating shared value (CSV). The thesis investigates this paradigm shift, aiming to understand the underlying dynamics and the impact CSV has on the company and its stakeholders. An analytical tool in form of a framew

One possible symptom of deficiency of folic acid (folate) or vitamin B 12 (cobalamin) is impaired cognition. Status of these two B-vitamins have been linked to cognitive performance also in various populations of subjects with no evident clinical deficiency (for example in "healthy elderly"). The present study investigated 60 nondemented patients (mean age 58 years) presented with mild c

The current expansion of mergers and acquisitions forces new postmerged organizational cultures to take form, and requires solid strategies for handling that procedure. Research indicate that at least half of all mergers fail in creating expected synergies, and that the reason for failing is assumed integration issues such as culture clashes. Creating a strong organizational culture is often appoi

Routine cleaning of water mains is commonly employed by water utilities around the world as a proactive means of managing common water quality issues. When employed correctly, water mains cleaning can be effective in removing loosely deposited sediments and bio films that cause water discolouration, coliform regrowth and unpleasant tastes and odours. Despite its long history in the water industry,

This paper deals with the question: "Why does the U.S. aid project to cambat HIV/AIDS in Africa, called PEPFAR, use a strategy that has been shown to be couterproductive?" The author uses an anthropological approach, based on theory of "aid as a gift" inspired by work of Mauss and Stirrat& Henkel. The study demonstrates that the interests that lie behind PEPFAR have had a g

The thesis integrates three different areas namely conflict prevention, human rights and NHRIs. The underlying assumption, that it is possible to prevent conflicts by implementing human rights, will be challenged. Furthermore, the human rights protection and the existing human rights machinery will be explored. The purpose is to examine and analyze if NHRIs are an efficient tool to implement human

This thesis investigates the issue whether States have a responsibility to regulate domestic companies, when those companies are violating human rights abroad. The assessment concerns the rights contained in the European Convention of Human Rights (ECHR) and the International Covenant on Civil and Political Rights (ICCPR). The first sub-issue of the thesis is whether these treaties can have extrat

In order to obtain biomarker values that reflect body burden of persistent organohalogen pollutants (POP), concentrations of lipophilic POP in serum or plasma are generally expressed on a lipid weight basis, and not on a fresh weight basis. There are two different approaches to determine the lipid content in serum and plasma. The gravimetric determination is more expensive, and longer experience i

Objective: to ascertain the significant factors that influence women to stop/not stop smoking during pregnancy and the postnatal period. Design: Twenty-four women were interviewed two-three years after delivery with regard to their smoking habits during and after pregnancy. The material was analysed based on a phenomenological approach in order to provide an accurate description of lived experienc

With its focus on gender, the aim of this study was to investigate the role of work locus of control (WLC) for job satisfaction and health in the context of occupational stress. Data were collected from 281 women and men at both managerial and non-managerial level in a Swedish telecom company. As hypothesized, external WLC was positively related to stressors and symptoms of ill-health, whereas it

Temperature not only has direct effects on microbial activity, but can also affect activity indirectly by changing the temperature dependency of the community. This would result in communities performing better over time in response to increased temperatures. We have for the first time studied the effect of soil temperature (5-50 degrees C) on the community adaptation of both bacterial (leucine in

Hypertension has been associated with increased case-fatality rates among individuals who subsequently suffer from acute coronary events. It is unknown whether inflammation modifies this relationship. This population-based study explored the effects of inflammation and hypertension on incidence of coronary event, and on the fatality of the future events. Blood pressure (BP) and five inflammation-s

Central-place foraging insects such as desert ants of the genus Cataglyphis use both path integration and landmarks to navigate during foraging excursions. The use of landmark information and a celestial system of reference for nest location was investigated by training desert ants returning from an artificial feeder to find the nest at one of four alternative positions located asymmetrically insi

One hundred fifty-eight Porous-Coated Anatomic (Howmedica, Rutherford, NJ) primary total knee prostheses were evaluated clinically and radiographically to measure the remaining thickness of the plastic insert. Anteroposterior radiographs were taken with the beam guided parallel to the tibial plate by a fluoroscope. The knees were forced into varus and valgus, and the heights of the medial and late

A cross-sectional investigation of 59 Swedish 7-9-year-olds with asthma and their parents was undertaken to study family factors of importance to the children's psychological adjustment. Children scored the I Think I Am questionnaire, a measure of global self-worth, parents the Child Behaviour Checklist (CBCL). Parents' report of family cohesion was assessed with the Family Climate questionnaire,

Papillomaviruses associated with clinical symptoms have been found in many vertebrate species. In this study, we have used an L1 gene consensus PCR test designed to detect a broad spectrum of human skin papillomaviruses to analyze swab samples from healthy skin of 111 animals belonging to 19 vertebrate species. In eight of the species, papillomavirus DNA was found with the following prevalences: c

Soil microorganisms, the central drivers of terrestrial Antarctic ecosystems, are being confronted with increasing temperatures as parts of the continent experience considerable warming. Here we determined short-term temperature dependencies of Antarctic soil bacterial community growth rates, using the leucine incorporation technique, in order to predict future changes in temperature sensitivity o
